The public tier takes NO credential at all; the subscription tier takes a credential that cannot be self-issued (it is granted after a licence is signed); and the identity provider that fronts the gated tier is a real, standards-compliant OAuth 2.0 / OIDC authorization server that publishes no public client registration path. summary: types: [none, oauth2, openIdConnect] api_key_in: [] oauth2_flows: [authorizationCode, implicit, clientCredentials, refreshToken, deviceCode, tokenExchange, jwtBearer, saml2Bearer, ciba, password] self_service_signup: false public_client_registration: false surfaces: - name: SLIP Public Services (ArcGIS REST) base: https://public-services.slip.wa.gov.au/public/rest auth: none evidence: url: https://public-services.slip.wa.gov.au/public/rest/info?f=json status: 200 probed: '2026-07-26' body: '{"authInfo":{"isTokenBasedSecurity":false}}' note: Confirmed anonymous — a live feature query returned real LGA boundary features with no credential. - name: SLIP Public OGC Services (WMS / WFS) base: https://public-services.slip.wa.gov.au/public/services auth: none evidence: url: https://public-services.slip.wa.gov.au/public/services/SLIP_Public_Services/Boundaries/MapServer/WMSServer?request=GetCapabilities&service=WMS status: 200 probed: '2026-07-26' - name: Data WA CKAN Action API base: https://catalogue.data.wa.gov.au/api/3/action auth: none (read) evidence: url: https://catalogue.data.wa.gov.au/api/3/action/status_show status: 200 probed: '2026-07-26' note: | Read actions are anonymous.
